Struct asn1::ObjectIdentifier

pub struct ObjectIdentifier { /* private fields */ }

Represents an ASN.1 OBJECT IDENTIFIER. ObjectIdentifiers are opaque, the only thing may be done with them is test if they are equal to another ObjectIdentifier. The generally recommended practice for handling them is to create some ObjectIdentifier constants with asn1::oid!() and then compare them with ObjectIdentifiers you get from parsing.

asn1::oid!() takes a series of arcs, for example: asn1::oid!(1, 2, 3).

rust-asn1 stores ObjectIdentifiers in a fixed-size buffer, therefore they are limited to OID values whose DER encoding fits into that buffer. This buffer is sufficiently large to fit all known publically known OIDs, so this should not affect most people.

Implementations

impl ObjectIdentifier

pub fn from_string(oid: &str) -> Option<ObjectIdentifier>

Parses an OID from a dotted string, e.g. "1.2.840.113549".

pub fn from_der(data: &[u8]) -> ParseResult<ObjectIdentifier>

Creates an ObjectIdentifier from its DER representation. This does not perform any allocations or copies.

Trait Implementations

impl Clone for ObjectIdentifier

fn clone(&self) -> ObjectIdentifier

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjectIdentifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ObjectIdentifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Converts an ObjectIdentifier to a dotted string, e.g. “1.2.840.113549”.

impl Hash for ObjectIdentifier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ObjectIdentifier

fn eq(&self, other: &ObjectIdentifier) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
